DOOR-HANGING MECHANISM.

Specification of Letters .Patent.

Patented Feb. 2, 1915.

Application filed May 13, 1913. Serial No. 767,250.

To all whom it may concern:

Be it known that I, JAoon J. Evans, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented new and useful Improvements in Door- I-Ianging Mechanism, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is an elevation of the side of a car, showing the car door in closed position with my improvements applied thereto; Fig. 2 is a section on lines II-II of Fig. 1; Fig. 3 is a detail of the door in closed position; and Fig. 4 is a detail of the door in slightly opened position.

My invention relates to mechanism for hanging doors, and provides a strong and durable construction for suspending the door and also prevents the door at its upper edge from sagging away or from being forced outwardly from the side of the car or other structure to which it is attached.

My invention also consists in the various parts which I shall hereinafter describe and claim.

Referring to the drawings, A indicates the car and B the car door. The door B is hung from and rolls upon a rail or channel 2, which extends across the front of the door and is attached to the car at its ends by the brackets 3. The door is secured to the rail 2 by the hangers 4 and 5, which are bolted to the door and in which the rollers 6 are mounted on integral trunnions 7. In the rear face of the hangers 4 and 5 are annular openings 8, through which the rollers 6 are inserted. The hangers 4 and 5 have hood-shaped flanges 9 which fit over the top of the door B.

Above the rear edge of the door opening is a bracket 10 which has a downwardly and inwardly extending L-shaped projection 11, adapted to engage outwardly extending lips 12 on the flanges 9 of the hangers 4 and 5. The lips 12 have the ends of their bearing facesbeveled, as is shown at 13, to facilitate the'engagement of the lips 12 with the projection 11. The bottom of the door is held against outward movement when in closed position by the brackets 14.

In assembling the mechanism the rollers 6 are inserted into the hangers 4 and 5 through the openings 8 and are positioned on the trunnions 7 the hangers are attached to the car door and the, rail 2 is then passed through the hangers and is bolted to the brackets 3. When the door is in closed position, as is shown in Figs. 1, 2 and 3, the lip 12 of the rear hanger 5 will engage the projection 11 of the bracket 10, thus relieving the rail at its unsupported middle section from a portion of the weight of the door B. If the rail has sagged the bracket 10 will raise the roller 5 out of supporting engagement with the rail and will relieve it of all of the weight of the door at this point, as is shown in Figs. 2 and 3. When the door is in opened position the lip 12 of the forward hanger 4 will engage the projection 11 of the bracket 10, and the middle section of the rail 2 will also in this position be relieved from excessive strain from the door at this point. As the rail 2 extends in front of the door, it will prevent the door from becoming detached from the car even though the hangers become broken or loose, and it will also prevent the bottom of the door from swinging outwardly to any considerable distance in case the brackets 14 become broken or inoperative.

It is obvious that various modifications may be made in the construction which I have shown and described herein without departing from my invention.

What I claim is:

1. In door hanging mechanism a rail attached to the structure at its ends and having an unsupported middle section, a door suspended from the rail by a plurality of hangers having roller bearings on the rail, and a bracket on the structure adapted to cooperate with a projection on the door to relieve the middle section of the rail from the weight of the door.

2. In door hanging mechanism a rail attached to the structure at its ends, and having an unsupported middle section, a door suspended from the rail by a plurality of hangers having roller hearings on the rail, a lip on each hanger, and a bracket on the. structure having a projection thereon adapted to cooperate with one of said lips to lift one of said hangers out of bearing contact with said rail when the door is closed and with the lip on the other hanger when the door is open, the said projection being adapted in both cases to relieve the middle section of the rail of the weight of the door.

3. In door hanging mechanism, a rail secured to the structure and a door suspended from the rail by a plurality of hangers, each hanger completely inclosing the rail and containing a roller mounted on a trunnion within the hanger, each roller being retained witlhin its hanger by a vertical face of said rai In door h nging m sm, ra l secured to the structure, and a door suspended from said rail by a plurality of hangers, each of said hangers completely inclosing the rail and having a roller therein adapted to bear on said rail, each roller being mounted in each hanger on a trunnion integral with the hanger and being insertible into the hanger through an aperture in the face of the hanger opposite to that with which the trunnion is made integral.

5. In door hanging mechanism, a rail secured to the structure, and a door suspended from said rail by a plurality of hangers, each of said hangers completely inclosing the rail and having a roller therein adapted to bear on said rail, each roller being mounted in each hanger on a trunnion integral With said hanger, and being retained in position upon said trunnion by a side of the rail.

6. In door hanging mechanism, a rail secured to the structure, and a door suspended from said rail by a' plurality of hangers, each of said hangers having a U-sha'ped flange extending over the upper edge of the door and downwardly on the rear side thereof, and being adapted to have a supporting engagement with a bracket mounted on the car.

7. In door hanging mechanism, a rail se-, cured to the structure, a door suspended from said rail between the rail and the struc-. ture, and a plurality of hangers mounted on said rail and securing the door to the rail, one of said hangers having a portion out of contact with the structure when the door is open, and having a supporting engagement with the structure when the door is closed, and another of said hangers having a supporting engagement with the structure when the door is fully open,

' tact with the structure when the door is closed.

8. In door hanging mechanism a rail attached to the structure at its ends andham ing an unsupported middle section, a door suspended from the rail by a hangers having roller bearings on the rail, and a bracket on the structure Copies of this patent may be obtained for five cents each, by addressing the V hanger secured to and being out of con-' plurality of adapted to I cooperate with a projection on the door to relieve the middle section of the rail from the weight of the door, a portion extending downwardly in front of the edge the door to prevent said door from bulging outwardly.

9 In door hanging mechanism, a rail supported on the structure by its ends only, a sliding door suspended from a recess in the outer face of said rail between the ends thereof and extending upwardly between said rail and the structure upon which it is supported, a slidable hanger lnclosing said rail and mounted on the outer face of said door, and a roller mounted in said hanger and held in position by the rail.

1d A hanger for sliding doors, having a rail inclosing portion, an opening in the rear face of said rail inc osing portion, and a trunnion on the opposite face, a roller adapted to be inserted through said opening into the rail inclosing space and beingjournaled therein upon said trunnion.

11. In door construction a rail having top and bottom flanges connected by a vertical wall, said flanges and wall forming a longitudinally extending channel, a door, a

said door, portion surrounding the rail, naled within said portion and adapted to roll in the channel of the rail.

12. In door construction, a rail having top and bottom flanges connected by a vertical wall, a door, and a. hanger secured to said door, said hanger having a portion surrounding the rail, a roller journaled in said portion between the vertical wall of the rail, and a wall of said portion, said roller being held on its journal by the Vertical wall of the rail and being adapted to roll on a flange of said rail. T a

13. Indoor construction, a door, a rail having top and bottom flanges connected by a vertiealwall, said flanges" and wall forming a longitudinally extending channel, the recess of which faces outwardly from the door, a hanger secured to said door, and

said bracket having and having a a roller jourhaving a portion surrounding the rail, a
